I stumbled across this Banksy mural in Park City, Utah today!
The Banksy has been there awhile and has been protected.
It is located in a non-descript ally not unlike this one.
Apparently Banksy had a film in the Sundance Festival in 2010.
I did some research upon returning Sundance.org
There are (were) seven Banksy works in Park City! I wish I had know before hand, I would have made the visit into a scavenger hunt.
